SWTPC 6800

[Brad H]

Okay this is where I was getting a bit confused -- I had gotten the impression that S1 records were essentially what was punched out on paper tape and that on loading back in, the teletype/paper tape reader was simply typing all this in as if someone was sitting there.  Looking at your TSC Basic file I see it invokes the memory examine and change function with the M and then starts at an address and just keeps going?

So when you had a program saved to a tape, these would have been S1 records encoded in Kansas City format?

Is there a large collection of these loader files somewhere?  Or like a definitive list of major software developed for the 6800?

I'm hoping to learn more on how to program these things -- I'm assuming there was an assembler people used rather than just modifying memory addresses?

Thanks

Brad

Brad,

You don't type in S1 records at the monitor prompt.  If anything you'd want to download a text file that simulates monitor commands to load memory,  but it's a lot slower.

I haven't been reading all of the posts in this thread, but have you tried following something like the instructions here to download a tape, I have documented how to use a terminal to download TSC BASIC into an SWTPC using a laptop serial port (or USB to Serial):
